The best solution would be to modify the Siesta program to directly
generate appropriate text files for performing atomic population analysis.
In addition to the cube file for Bader analysis, it would be useful to get
output of a single file that contains the valence electron density grid,
spin density grid, number of core electrons replaced by pseudopotential on
each atom, the atomic coordinates, atomic numbers, net charge of the unit
cell, and the number of periodic lattice vectors. For periodic directions,
the density grid should be commensurate with the lattice vector along that
direction. A file containing this information would allow Siesta users to
run a program to compute Density Derived Electrostatic and Chemical (DDEC)
net atomic charges, atomic dipoles and quadrupoles, atomic spin moments,
and effective bond orders. This should be set up so that a keyword can be
placed in the Siesta input file to direct the Siesta program to output the
file at the end of a calculation before the program terminates. If one of
the Siesta developers is interested in programming this capability, please
contact me directly ([email protected]) and I can assist with specifying file
format requirements and analyzing test runs.
